The pad is easily applied in the shoe and apreferable method being to first fold the holder at the neck to form acrease mark at the exact center to line with the back seam'of the shoequarters uniformly disposing the discs at relative opposite sides fromsuch seam and dei'l nitely locate the same at the proper position withrespect to the heel of the foot.

A coating of vulcanizing cement is appliedover they entire rear surfaceof the holder and disc and then placed in theshoe with the tabs bent totuck beneath the sock-lining and lap upon the top surface of the innersole. The pad is readilyand easily fitted intothe shoe-and 'a pair ofpads are usually merchandised with a small tube of cement although it ispossible to merchandise the productwith its rear side coated with aremoistening adhesive. The use 01' a vulcanizing cement, however,produces a more durable adhesion which is not apt, to loosen from theheat and moisture of the foot, I

In making the disc from a sponge rubber stock in which the pores arevery small, a very soft velvet-like friction surface isobtained whichwill hold the shoe to the foot against slipping, preventing any rubbingaction upon the foot or stocking, avoiding injury to the foot and wearto the stocking and the yielding characteristics of the pad or discoffer considerable comfort to the foot. y

Having described my invention, I claim:
